Product Details

Entropy Clear Casting Fast Hardener (CCF) should be mixed with Entropy Clear Casting Epoxy Resin (CCR) for low build casting applications with thicknesses below 1 inch.

Clear Casting Epoxy Resin (CCR) features low color, excellent air release, and UV stabilizer technology. The result is crystal clear products with excellent color stability. These traits are highly desirable for jewelry, furniture and bar top applications.

Use CCR Resin with CCF fast hardener at a 2:1 mix ratio for medium pot life. For larger castings greater than 1 inch thick, the CCS Slow hardener is recommended instead. The clear casting resin CCR and CCF Hardener have a bio-content greater than 30%, and can be modified with epoxy compatible colorants and fillers.

CCF hardener requires the corresponding size of CCR Epoxy Resin for use (2:1 mix ratio). See chart below.

Info & Guides

IMPORTANT! Entropy Clear Casting Fast Hardener (CCF) should be used ONLY for low-volume (less than 1 pint) casting applications with thicknesses less than 1 inch. Using CCF Fast Hardener for larger volumes or greater thicknesses can result in exothermic cures that will damage the resin. For mass castings with thicknesses greater than 1 inch, use Clear Casting Slow Hardener (CCS).

NOTE: Exact fill weight of 5 Gallon CCF Hardener is 4.783 gallons.

Safety and Handling Information

Despite the natural derivation of Entropy resin products, exposure to these materials represents hazards typical of all epoxy resins. Exposure should be minimized and avoided through the use of proper personal protective clothing & equipment, and appropriate manufacturing controls. All persons who use, store, or transport these materials should understand proper handling precautions and recommendations, as stated in the SDS (safety data sheets).
